WHAT IS "VICON" ?
PRODUCTION METHOD FOR PRECAST CONCRETE
There are three major production methods for precast concrete; centrifugal, wet-cast, and dry-cast concrete. Centrifugal and wet-cast have been commonly used in Japanese concrete industry for quite long time. On the other hand, dry-cast or semi-dry cast was yet new and challenging when we first brought the idea to Japan in 1960's.
WE ARE THE PIONEER OF VICON CONCRETE
A main feature of Semi-dry cast concrete is having a low water to cement ratio . A dry-casting machine compacts such solid concrete in vibration which provides the concrete temporary liquidity and compress it from the top as finishing. The name, "VICON " is a Japanese registered trademark for semi-dry cast products , which is named after "VIbration", "COmpression" and "CONcrete".
ITOYOGYO and VICON
| 1961 | The founder, Goji Ito visited Europe and got inspired by semi-dry cast concrete |
|---|---|
| 1965 | VICON Group was established by 50 companies as its member |
| 1967 | Installation of a semi-dry pipe casting machine |
| 1976 | VICON Group grew into VICON National Association. Goji Ito was assigned as president of the association. |

VICON QUALITY
VICON concrete is very dry, so the molds can be stripped immediately after the concrete has been consolidated. For this feature, VICON is capable for mass production. Also, it contains minimum water, VICON concrete is known for high durability with resistance to carbonation, freeze-thawing, and chemicals.
ANTI-CARBONATION
An accelerated carbonation test was performed under the condition that carbon dioxide concentration was 10%
ANTI-FREEZE THAWING
An accelerated carbonation test was performed under the condition that carbon dioxide concentration was 10%
CHEMICAL RESISTANCE
Accelerated freeze-thawing test evaluates resistance to frost damage of concrete.
The test provides the cycle of temperature >18-5 degrees Celsius to accelerate degradation of concrete and the testing results show that VICON concrete has higher durability than other concrete.
